A heart is more than a beat per second.
When it beats, it tells you something.
You're a human being who breathes air, and exhales it out.
Your breath can't be taken away, but can stop.
When your heart beats faster than normal, it's telling you danger's coming.
It may also mean you're very excited,
but you start to beat slowly.
You're not glad, but gloomy.
The phrase, "You're heart is aching" isn't the right word,
but more like disappointed, is what your feelings should be described as walk away, and fight the urge to sob, until you can get somewhere comfortable,
and cry.
A heart is more than a beat pear second.
It tells that you're a human being, and you deserve to breathe in and breathe out.
